Do you have a graph to display the A/F ratio?

I've run E-85 for 8 months now and can't say enough about it... It's the best of all worlds, and, as already stated, works VERY well in F.I. applications, although it works well in N/A applications as well. Though to truly take advantage of E-85 in an N/A setup you should bump the compression up. 13:1 seems to be the sweet spot on LS N/A applications running E-85...

So if I go to my tuner and say I want to run E85 all I have to do is dump E85 in the tank and tune it.....
So if I put a full exhaust and intake on I can tune it with e85 and be around 450 460rwhp..with my stock injector ls3....It sounds to good to be true.

Clearly you got great gains, however I'm curious as to the gains on a car like mine...
I'm already tuned well for 93oct with full exhaust, and CAI. I make in the 420's rwhp, for the change to be worth it to me I'd want to see at least a 20rwhp gain across the RPM range, too bad so few have done this.
It would be completely sick to have just a full exhaust car making 440+ to the rear wheels.

Every NA car I have done has made around 3% more power with just E85. It has to do with the amount of BTUs you burn, E85 has less BTUs then gasoline but you use allot more of it hence the power gains.

Well it seems that the factory fuel system can handle up to 500whp on e85 when looking at the 08 ZO6 (same fuel system as LS3). With full exhaust and intake I bet you would be close if not over 440whp. The fact is, this is real and none of these older corvette guys are even thinking to look this way.
The turbo market is all over e85 and it's actually better for your car (cheap race gas). I'm getting ready to tune my factory NPP LS3 MN6 car and will expect over 420whp BONE STOCK.
If anyone wants to do this let me know as my tuner can get the job done.

You then tune the car as any other.
FI cars run a magnafuel pump good to 2000hp (1300 on E85) and appropriate injectors.

Assume 30% more fuel. It's simple math. If your Injectors and Fuel pump can support that with alittle to spare than you can dump it in and tune it; of course taking note of the stoichiometric values.

Nobody's has mentioned the biggest GAIN from running E85 on N/A cars...
Its the sever COOLING effect for people like us in hot states like AZ and Nevada....
Bottom line you can beat the summer heat if you wanted too...unless you have special powers and weather controlling mind tricks that would put you on the next TOSH.O episode...
The gains shown above are nice.... However you cant put a price on having winter weather driving to an extent during the summer months...
MPG or whatever issue people want to debut here is pointless when you factor in the heat dissipation and having less performance driving during mind blowing heat that takes away from the driving experience!
